' UNITED STATES PATENT OFFICE 2,031,298 I ELECTRIC ro'mmza'roa Francis Tatlock Bolas and Liverpool, England,

, John William McClew, assignors to Automatic Electric Company Limited, a British company Application October 17, 1930, Serial No. 489,266 In Great BrltainNovember 13, 1929 6 Claims. I (01. ass-92) present invention is particularly adaptable foruse wherever it is desired to totalize values of different denominations according to class such as at theatres, coliseums, race-courses, and the like, where rapid selling of different values of tickets of different descriptions or classes takes place. For purposes of illustration, the present I invention is being described in connection with the totalizing of tickets sold in connection with horse-racing.

It will be recalled ment the connections between the ticket-issuing a constantly rotating switch, the wipers of which were connected in mulgple Wt the switches 30 associated with the other ticket-issulng machines,

so that when a contact marked. in accordance with a sale of a ticket on a particular runner was encountered, the necessary signal was transmitted to the totalizing machine associated with that 5 runner. The wipers of the various switches, how: ever, were given a special phase relationship so that no two switches would be in a position to register salesof' tickets for the same runner at the same instant. 3 'According to one feature of the invention, greater speed of working is attained in that in an electric totalizator employing rotating collecting switches for collecting indications from a plurality of transmitting stations, indications are collected simultaneously over different wipers of the same switch which may bear any desired phaserelationship and hence will preferably be 7 in alignment.

According to another feature of the invention, in an electric totalizator employingrotating collecting switches, each corresponding to a partic-' 'ular indication, for collecting indications from a plurality of transmitting stations, indications of different values are collected simultaneously over diilerent wipers of the same collecting switch.

that in the prior arrange- I machine and the central equipment was made A further feature of the invention closely related to the features Just mentioned is that in an electric totalizator having indications transmit--. ted from. a plurality of transmitting stations, in-

dications of one character are stored on a relay 5 I group, .theregistration of a predetermined num-. ber of indications serving to effect a marking in the bank of a collecting switch corresponding to indications of higher denomination.

The invention will'be better understood from 10 the following description of one method of carrying it into effect which as a matter of convenience in description assumes "its use in connection with horse racing. This description is given by way of example and should be taken in conjunction 5 with the accompanying drawings of which Figs. 1-17, when fitted together in the manner indicated in Fig. 19, show the complete circuits of a totalizator installation, while Fig. 18 shows schematically the general layout.

A description will first be given of the general operation of the installation with reference to Fig. 18, which shows a trunking diagram of the apparatus involved in the collecting of markings corresponding to the sales of tickets on one particular horse from 200 ticket-issuing machines of diiferent denominations, comprising 100 machines of 2/- denomination and 25 machines each of 10/-, 1, 10,and 100 denomination.

Assuming that the operator at the 2/- ticketissuing machine SM receives a request for a 2/- ticket for a win on horse No. 1, he will operate the appropriate horse key on the ticket machine and will also move a common win or place key to the win" position whereupon both keys are locked in their operated positions and a signal is transmitted in code to a decoding relay group designated DCRI in the main totalizing equipment. When this has been done, a marking is extended from the relay group DCRI to the 'ap- 40 propriate bank contact of the horse collecting switch HCS which is in continuous rotation in order to find'such markings. The horse collecting switch HCS shown is assumed to be that for collecting sales of win tickets on horse No. 1 and is provided with eight banks and associated wipers over which sales markings may be collected from as many as 200 machines of different denominations since each bank, comprises 25 contacts. Whenthe topmost wiper of the switch HCS encounters the marking from the decoding relay group in question, a storing relay will be operated in the 2/ storing group designated SGI to register one unit, and at the same time a relay is operated in the decoding relay group DCRI. s5

I This causes a signal 1 to the 1 counting switch, the collecting operlated 1 collecting switch to be extended back over the leads to the ticket-issuing machine to initiate the ticket-issuing operation thereat, and when this is completedthe keyswhich were locked in their operated positions are released. A similar then automatically marking is extended over conductor ID to the appropriate bank contact of a switch similar to total win totalizer,

HCS associated with the which also rotates to find this marking and operate an appropriate storing relay in a group similar to SGI associated with the "total win totalizer. In a similar manner markings will be collected from other bank contacts of the switch HCS which are associated .with other decoding relay groups similar to DCRI, and when 10 such units have been registered on. the storing relays in the group SGI, a marking is extended to the banks oi the trans- I'P, which thereupon rotates to find the marking and operate the driving magnet of the 1 counting switch PCS accordingly. During the-transfer oi the translated ation of the horse collecting switch HCS is temporarily suspended, and does not recommence until the storing relays in the group SGI have been released after the 1 marking has beenduly registered. v

In similar manner ticket sales markings from the 10/- machine TM are registered on the 10/- decoding relay group DCR2 and from there will be collected-over a different wiper oi the switch HCS Each time two such units Markings are also extended from the 1, 10

and 100 decoding relay groups, but, asthe trafiic anticipated irom these machines is not likely to be heavy, storing relay pensed with and, in this case, the markings are extended direct to the associated cpunting switches PCS, TPS and HPS by way of the lower wipers of the switch HCS. I It will be understood that, when the 1 counting switch PCS has made 10 steps, thereby registering the equivalent of 10 separate sales of 1 tickets, an impulse is extended to the driving magnet of the 10 counting switch TPS, and similarly when this switch has made 10 steps an impulse is extended to the driving magnet of the 100 counting switch I-IPS. It is likely, therefore, that at some period in the operation of the circuit, impulses will be extended to the counting switches 'fromthe direct source by way or the collecting switch H05, and also from the indirect source by way of the translated 1 switch TP, or alternatively, the counting switch 01 the preceding digit. Hence, in order to prevent the two markings from becoming confused, means'are provided whereby the marking from the direct source will always take precedence over that from the indirect source, and until both have beenv duly registered the operation of the horse collecting switch HCS is temporarily suspended." Y

When the end of the ticket selling period is reached and the ticket-issuing machines are locked to prevent the issue of further tickets for groups have been disthe particular race, it storing relays in the groups such as SGI and 8G3 will be in operated position; and the sales of tickets they represent will not have been registered on the main totalizing equipment, since as was previously explained it is necessary to store is probable that various a definite number of such units before the trans- 'lated 1 switch TP is brought into operation to transfer the marking on to the 1 counting switch PCS. Consequently, when the selling is stopped and the ticket machines are locked, the stored units collecting switch in order to collect up outstanding markings from SUC is caused to rotate each storing relay in the group in turn, and

transfer them to the magnet of the 2/- counting switch 'I'WS, so that the remainder of the ticket sales .on this particular horse will be added to the display on both the horse and total indicators. It should also be mentioned that a'10/- counting switch TSS is provided and, .in case the trailic from the 10/- machines was not unduly heavy, the storing group'SG3 might be dispensed with and the markings could then be extended direct to the magnet of the 10/.- counting switch. With the arrangement shown, however, indications from the ,2/- counting switch TWS are passed by way of the 10/- counting switch TSS to the 1 counting switch PCS, and it will be noticed that the l0/- and 2/- are arranged to display on a single indicaton the alternate positions of. the 10/-' switchservingto operate a relay which advances the number displayed on the indicator by five units.

In case the ticket request had been for a place instead of for a win, the win or place key would have been operated to the place position, thereby effecting the operation of a switching relay P at the main totalizing equipment which would transfer all the signalling leads extending from the ticket-issuing machine to another decoding relay group on ed to the appropriate bank contacts of another horse collecting switch similar to HCS associated with the place totalizing equipment. In a similar manner the place decoding relay groupwould extenda marking to the bank of a further collecting switch associated with the total placetotalizer.

If it is desired to set up a ticket sale on a horse in the 4I80 group, a separate ticket issuing machine will be used which is connected in parallel with the 1-40 machine so that the-same coding leads may be used in each case. The operation of the win or place key of this. machine in either direction, however, completes the circuit 1 of a relay designated CO in the main totalizing equipment to change over the code leads on to another decoding relay-group capable of setting up markings on the switches "-80.

The general operation of the installation having been briefly described, a scription will now be given, reference being had to the annexed drawings of which Figs. 1 and 2 banks of horse cgllecting show the electrical connections at a typical l-ll ticket-issuing machine in which accordingly the springs 01' the win or place" key' for efiecting the operation 01 relay FEC are unwired. Figs. 1 and 2 also show the. arrangements whereby a number of machines may be automatically locked 'or unlocked at will mm a central point. Figs. 3, 4 and 5 show the win decoding relay group associated with the ticket-issuing machine of Figs. 1 and 2, andalso the change-over relays PB and EEC which serve respectively to change over the counting switches detailed circuit de-
